v To all whom itJIMI/y concern:

- Beitknownthatl, NATHAN THOMPSON, of AbbeyGardens, St. Johns Wood,in the county of Middlesex, England, a citizen of the United States of America, have invented or discovcred new and useful Improvements in Stoppers for Bottles, Jars, Vessels, and Tubes, alsofor Ordinance and Fire Arms; and I, the said NATHAN THOMPSON, do hereby declare the nature 'of tliesaid invention'and in what manner the same is to be performed to be partie-=' ularly described and ascertained in 'andby the following statement there f-.that is to say:

This invention has-for its object improvements in stoppers for bottles, jars, vessels, and tubes, also for'ordnance and fire-arms; and it consists in constructing a stopper of airing of a soft, yielding, elastic substance placed between two disks or parts, an upper and a lower one, to one of which is hinged or jointed a lever which, when turned on its hinges or axis, is' caused to act on the other part in such manner 'as tomove the two parts toward each other. \Vhen the disks'or parts are drawn toward each other, by turning the lever-they compress the elastic material between them and cause it to bulge or protrudeoutward all around the disks or parts; and the lever is so formed as to retain the parts from again separating until the lever is turned to allow them to do so. v

, .In the drawings hereuntoannexed I have shown examples of stoppers constructed as above described; but I would have it under-- between the upper and lower parts of the. stopper; 1), the lever by which the parts are drawn toward each other in order to compress the ring, and by which the parts are retained in this position.- The lower part ofthe stop;

. per; is composed of three piecesof metal, 0, d,

and a, stamped in dies from sheet metal to the form shown in Figs. 1, 5, and 6,- tin-plate being by preference the sheet metal employed.

The plate 0 is-dishedinward, as is shown in the-section, Fig-. 4, in order that it may.- be

of-suflicient strength. Through the slot in the center of-thisplate is passed the hooked por;

tion of the piece (Z, and the piece d ishel'd 'there by,avsmall portion of the metal at each end of the slot being pressed into the small notches cl in the piece d. The under side of the piece 0 is then covered over with the covering disk or plate 6. itself covered over with a disk of thin sheettin, and over this disk of fabric, or in place of this, thecovering-plate einay itself be com-'- posed of sheet-timand this maybe covered with enamel or otherwise protected, if desired.

The so covering the under side of the stopper with tin prevents the stopper being corroded if it be applied to bottles containing acid sub: stances. In placeof so covering the under surface ofthe stopper it may be otherwise.

covered or protected.

scribed, by means of dies or instruments such as are used in'the manufacture of buttons,

when the bottom of ,the stopper is covered with a coating of tin and of fabric. This is done by placing a disk such as is shown at Fig. 7

V of the collodionized fabric in a suitable hollow die, and over this is placeda disk of tin-foil or thin sheettin. The piece 6 is then placed .above it, the projecting ring being upward. The edges of the disks of fabric and tin are then by the tools or dies turned over the piece 6, and the combined pieces a and d are placed above it, (the edges of the piece c resting on the turned-over edges of the disks.) The flange of the piece 0 is. then by the dies turned or thrown over onto the flange of the piece a, i

and thus the pieces are connected together and'the' edges of the disks of sheet-tin and fabric also secured.

The upper, part of the stopper is composed of three pieces, f, g, and h, shown separately at Figs. 8, 9, and ll). Each of the pieces is stamped separately intothe formshownin each of these figures. The pieces are then V001), M DDnEsEX" At the same time thedisk e is The parts are put together," as aboye. de=

connected together and also connected to the lower part of. the stopper in the follow-- ing manner: The ring f is placed on the upper surface of the bottom. part of the stopper. The piece which is the piece upon which the thrust of the lever 11 is tak'en,is placed into the ring, the hook d of the lowerpart of thestop per passing up through the slot in this piece. The lever- 22 is then hooked on to the hook at. The covering-plate h is placed over the-ring f, and the lever is turned down, so as to lie within the recess in the plate h. The parts so put together are then placed in a hollow die, the lever and plate h being downward. The edge ofthis plate is then by the dies turned or thrown overthe projecting ring or flange at thetop of the ring f. The hopper is then complete.- The manner of constructing the lever b is shown atFigs. 11, 12, and 13." 1 Fig. 11 shows views of the lever b when completed. The lever is made from a piece of sheet metal of the form shown at Fig. 12. The piece of metal so formed is first bent over into the form shown at Fig. 13, and the slot through which the hook dis to pass is then pierced through it, so bringing the piece of metal to .the form shown at Fig. 11.

Asimilar stopper to' that above described is shown atFigs. 14, 15, 16, and 17. The upper and lower parts of this stopper are, how- ,ever, of wood in place of being of metal, as in the stopper first described. a is the ring of vulcanizedindia-rubber; b, the lever; c and c, the upper and lower parts, respectively, between which the ring iscom'pressed. Through the center of the lowerv part, 0., "is a' hole, through which is passed the pieced, similar to the piece (1 in the" stopper first described; This piece may be cemented into its place with a suitable cement. I When-the two parts 0 and c of the stopper are placed together, the piece d, which projects upward .-from'the part c, rises up through an opening in the center, of the part'c. The lever bis then hooked onto the hook on the top of the piece d, and into the end of the slot or recess in the upper suriac'e of the piece o is cemented a smal-lstrip of wood or other material to prevent the lever .b from coming oif the hook. When this is done, the india-rubber ring e-is stretched into its place around. the part c,-when the lever is turned upward, and the 'rstopper; is then complete.

At Fig. 18 is showna stopper similar to the one last described, applied asa tompion for Both of N0. 17 Graccchm-ckStreet. London, E. O.-

stopping the muzzle of a cannon. Figs. 1 9,

c is the ring .of vulcanized indie-i rubber or other elastic material, and d the lever hinged to thelower part, b, of the stopper.

Separate views of the lever d are shown at r Fig. 22, from which figure it will be seen that the lever is composed of a semicircular flap,

having slots d through it, by which it is hinged to the part'b, and also having two small projections, (1 which act on the surface or ring a of the upper part, a, of the stopper.

At Figs. 25 and 24 is shown another example of a stopper constructed according to my invention, Fig. 23 being a side view, and Fig. 2 4. a vertical section, of the stopper.

In this case the upper andlower parts of the stopper are drawn closest together when the lever is in a vertical position, in place of being closest together when the lever'is in a. horizontal position, as in the other stoppers before described. a is the upper, and b the lower, part of the stopper; 0, the ring of vulcanize'd' india-ru'bber, and d the lever which is connected to the lower part, b, by a .pin carried by it passing through a slotin' the part b.

Having thus described the nature of myiin vention and the manner of performing the same, I would have it understood that what 1 claim is-- 1. Constructing stoppers-of an elastic ring interposed between two parts, which are so combined with a leverthat the parts may be -moved to or from each other by the lever, as

above described.

2. Forming the upper p'art of the stopper so constructed with a projecting ring of larger diameter than the mouth of the bottle or other article to which the stopper is to be applied.

3. A recess in said top for thelever to lie in. 4. The connecting the lever to the lower part of the-stopper by a hook, as above described;
